3. General descriptionThe electronic braking devices of the VersiBrake-L-type are available both as a housing version and as a circuit-board version (LP). They enable non-wearing braking of three-phase asynchronous motors and mono-phase motors. The braking devices are used for drives that, due to safety and functional reasons, have to be reliably slowed down. Braking is initiated by measuring the motor voltage. It is not necessary to connect the motor contactor contact, but this is possible if double detection (redundant system) is required. An integrated standstill detection function switches the braking current off after the motor has come to a standstill. In the case of motor braking times larger than 3 s, this also functions without leading the third motor phase (6T3-terminal) back.Various fault conditions are indicated via LEDs and, in the case of the circuit-board version, additi-onally via a fault signalling contact.

Special features• controlled by microcontroller• wear-resistant and maintenance-free• for three-phase asynchronous motors• for mono-phase motors• retrofitting into existing plants possible• no normally closed contact on motor contactor required• integrated braking contactor• printed circuit-board version with fault signalling contact• automatic remanence time optimization• integrated motor standstill detection• integrated overload monitoring• braking current control• meets trade association requirements for category 2 according to EN 954-1 according to

the test principles of woodworking machines GS-HO-01

4. Usage to the intended purposeThe devices of the VersiBrake…-L (LP)-series are electrical equipment that is used in industrial electrical power installations. They are designed for application in machines, in order to slow down rotating masses on drives with three-phase a.c. motors.

Typical applications• sawing machines• centrifuges• wood working machines• conveying systems• textile machines

7. Functional description (see connection diagram)

Explanation: The designations for the housing variant are indicated without brackets, whereas those applicable for the circuit-board version are put into brackets.

After the operating voltage on 1L1 (L1) and 3L2 (L2) has been switched on, the main contactor interlock X5 (X5), X6 (X6) and, in the case of the circuit-board version, the fault signaling contact (X10), (X11) closes. The motor can be started.A starting logic makes sure that, when switching the plant on with the master switch while the motor is still switched off, braking is not initiated.The fully automatic run of the braking interval starts when a drop of the motor voltage is detected on the terminals 2T1 (T1), 4T2 (T2) and 6T3 (T3). During braking, the main contactor is inter-locked via the contact X5 (X5), X6 (X6). After a delay time which, dependent on the amount of the remanent voltage of the motor, optimizes itself, the integrated braking relay pulls in. After the contact bounce time has been waited out, a controlled d.c. current is fed into the motor winding. The magnetic field resulting from this has a braking effect on the still rotating rotor. The d.c. current is generated by a thyristor phase control. Special suppressor circuits protect the power semiconductors against overvoltage. With the potentiometer I (P2), the braking current (and thus the braking torque) can be adjusted within a range of 10 … 100% of the rated device current. The integrated motor standstill detection, which, if the 6T3 (T3)-terminal is connected, functions via the amount of the remanent voltage and, if the 6T3 (T3)-terminal is not connected, via the brake current waveform, switches the braking current off approx. 1.5s after a motor standstill has been detected. To be able to adapt the device to a variety of motors, it is possible to adjust the stand-still threshold via the potentiometer n0 (P1). Faults, that occur during braking, are indicated via a signaling light (LED), and, in the case of the circuit-board version, additionally via a fault signaling output (X10), (X11).If more safety (redundant system) is required for initiating braking, it is possible to additionally connect a normally closed contact of the motor contactor to the terminals X3 (X1), X4 (X2). Then, braking will be initiated by two processes which are independent of each other.

Warning:

To ensure a reliable standstill detection function, it is necessary to comply with the following:The braking current must not exceed (3) three times the amount of the rated motor current. If the VB-L is operated without the 6T3 (T3)-terminal beeing connected, which always applies in the case of single-phase applications, it is to be ensured that braking current flows at least for a period of 1.5 s before the motor comes to a standstill, as no motor standstill is detected within this period of 1.5s and the braking current would then flow over the total maximum braking time. This could cause destruction of the motor and fault indications of the braking device.

Note: If the braking time at rated device current is too short, due to the fact that the centrifugal masses to be slowed down are too large, either a device with a longer braking time can be inquired of the producer or a device featuring a higher rated current has to be used.

8. Control inputs and outputs

8.1 Control input

Information on operation without connected starting contact:The braking delay time (remanence time) may prolong itself by up to 50%.The interlocking relay does not open immediately after the motor contactor has dropped out, but only shortly before the braking relay closes. In contrast to an operation with connected starting contact this means that the motor can be restarted during the braking delay time (remanence time).

Caution: Danger to life through electric shock!

The terminals X3 (X1), X4 (X2) carry mains potential; when laying the connecting lines, be sure to provide protection against accidental contact.

Interlock (potential-free changeover contact, common contact on X5)

During braking, the contact between X5 and X6 is open. This contact is to be looped into the control circuit of the motor contactor. Therefore, the motor cannot be started during braking. The contact between X5 and X7 is closed during braking. Thus, it is, e.g. in the case of star-delta-connections, possible during braking to control the star contactor in order to interconnect the motor winding.For more detailed information, please see connection diagram on page 20.

9. PotentiometersWith the potentiometers it is possible to adjust the following parameters. The designations for the circuit-board version (LP) are indicated in brackets ().

Note! If the potentiometer is adjusted to a position too far in clockwise or counter-clockwise direction (e.g., end stop position), it may happen that no standstills are detected. In this case, braking current flows until the end of the max. braking time. The LED indicates „no standstill during the max. braking time“.

„I“, „(P2)“ Adjusting the braking current. The braking current can be adjusted in the range from approx. 10% - 100% of the rated device current. The adjustment is roughly linear.

„n0“, „(P1)“ Adapting the standstill threshold and braking behavior at motor standstill.With this potentiometer it is possible to adapt the motor standstill threshold to various motor types and applications and to influence the behavior of the braking current at motor standstill.In „left stop“ (full counter-clockwise) position, the standstill detection function is most sensitive, and the braking behavior, upon reaching the motor standstill, is most soft. Possibly, the braking current is switched off even before the motor has come to a standstill. The potentiometer has to be adjusted so that the braking current is switched off approx. 1-1.5s after the motor has come to a standstill.Factory-setting: approx. 40%.

11. CommissioningThe device is to be put into operation in 3 steps:

1. Mounting2. Connection and3. Parameter setting

11.1 Mounting instructions

Caution: Danger to life through electric shock!

The following conditions are to be complied with in order to ensure a safe and reliable operation of the VersiBrake…-L (LP).

1. The device series VersiBrake…-L (LP) is to be used under overvoltage conditions of the category III.

2. Make sure that pollution degree 2 or better, in accordance with IEC664, is complied with.

3. The device is to be installed into a housing (min. degree of protection: IP54).4. The device must be operated without being exposed to contamination by

water, oil, carbon deposits, dust, etc..

Warning:

Make sure that a minimum distance to adjoining devices is kept. Above and underneath the housing a minimum distance of 50mm is to be kept.

11.2 ConnectionThe braking device is to be installed according to the attached connection diagram. For other connections please consult PETER electronic GmbH & Co. KG.

Note: Further connection proposals for special circuit arrangements are available via our homepage at www.peter-electronic.com.

Note: Prior to putting the motor brake into operation the wiring is to be checked.

To ensure reliable function is it necessary to comply with the interlocking conditions:The interlocking contact of the braking device, terminal X5 (X5), X6 (X6), has to be looped into the control circuit of the motor contactor, in order to prevent the motor contactor from pulling in during braking.

14 VB230/400-6/25/30L (LP)

11.3 Parameter settingsSequence of steps during commissioning: (the designations/details indicated in brackets refer to the circuit-board version)

1. Disconnect the plant/system from the supply mains.2. Adjust the requested braking current with the potentiometer „I“, „(P2)“.

Since the potentiometer reacts roughly linear, it is possible to infer the braking current from the potentiometer setting. Left stop (counter-clockwise direction) roughly equals 10% of the rated device current. Mid-position roughly equals 50% of the rated device current. Right stop (clockwise direction) equals 100% of the rated device current.

3. Adjust potentiometer „n0“, „(P1)“ to approx. 40%.4. Switch on the plant.5. Initiate braking by switching the motor ON/OFF.

Note: When putting the device into operation for the first time, the braking current can be checked with a true r.m.s. measuring instrument.

Adjusting the braking currentThe braking current is to be adjusted to a value as small as possible, in order to avoid unnecessary heating of the power semiconductors and motor. This is especially important in the case of high switching frequencies. We recommend to limit the max. braking current to 2.5 times the rated motor current.The requested braking torque can be adjusted with the potentiometer „I“, „(P2)".

Adjusting the braking timeNo adjustments are required, since the braking current is automatically switched off approx. 1.5s after a motor standstill has been detected.If no standstill is detected during the max. braking time (10s in the case of standard devices), the braking current is switched off when this time is over. This case is indicated by the LED „ready“, „(V9)“ (flashing 1x).

VB230/400-6/25/30L (LP) 15

Adjusting the standstill thresholdIn most applications, the factory-setting (40%) produces good results.If the braking current is switched off before the motor has come to a rest, or if the braking current is not switched off approx. 1.5s after the motor has come to a rest, it is possible to make an adjustment with this potentiometer. The optimum setting has to be found by carrying out several braking operations. The potentiometer should be changed only in little steps (10%). For a more detailed functional description please refer to page 9.

Warning:

If the 6T3-terminal is not connected, the motor has to be supplied with current for a period of at least 1.5s prior to the standstill. During this period of 1.5s no motor standstill is detected. The braking current then flows until the maximum braking time has elapsed. If this is the case, the braking current has to be adjusted to a slightly lower value.

16 VB230/400-6/25/30L (LP)

11.4 Possible fault indications during commissioningDuring commissioning, and in normal operation too, fault indications can occur. The following explanation is to give you assistance in the localization and correction of faults.

Note: All data sheets and commissioning instructions are available via our homepage at www.peter-electronic.com.

Fault indication on LED „Ready“, „(V9)“

Fault Possible cause Fault correction

Flashing 1x No motor standstill during max. braking time

Braking current adjusted to a too small value.

Adjust braking current to a higher value.

Too large centrifugal mass. Use a braking device with longer max. braking time or higher rated device current.

Terminal „6T3“ „(T3)“ is not connected and the motor is not suplied with current for a period of 1,5s prior to the standstill.

If possible, connect 6T3 (T3) or adjust the braking current to a slightly lower value.

Standstill threshold is not adapted.

Adapt standstill threshold with „n0“.

Flashing 2x Adjusted braking current was not reached.

Interruption in the braking circuit. Possibly the motor is started with star-delta connection.

Check circuit. Possibly the star contactor has to be closed during braking.

The resistance of the motor winding is too high for the adjusted braking current.

Turn braking current back so that the fault does not occur any more.

Flashing 3x Braking device is overloaded. Braking frequency is too high.

The specified max. braking frequency is exceeded.

Reduce braking current or braking frequency. During commissioning, 4 braking operations in succession can be initiated without an overload being indicated.

Flashing 5x 3x in succession no standstill detected

Braking current adjusted to a too small value.

Adjust braking current to higher value.

Centrifugal mass is too large. Use braking device with longer max. braking time or higher rated device current.

Connect or check cable.

Standstill threshold is not adapted.

Adapt standstill threshold with „n0“.

VB230/400-6/25/30L (LP) 17

12. Dimensioning rules

Note! All data sheets and commissioning instructions are avaialble on our homepage at www.peter-electronic.com.

12.1 Dimensioning of braking contactorsThe braking contactor is switched on or off via a control contact of the braking device (no-load switching).When selecting the braking contactor, it must be ensured that the contacts are able to carry the maximally occuring braking current (nominal/rated device current). Therefore, the value „conven-tional thermal current“ (Ith) is decisive when selecting the braking contactor.If this value is not indicated, the rated operational current for AC1-operation may be used instead.

Tip: By connecting contacts in parallel it is often possible to use a lower-priced contactor of a smaller design.

12.2 Dimensioning of pre-fusesBasically, two types of fuse protection are available for the user.

1. Fusing according to allocation type „1“, DIN EN 60947-4-2. After a short circuit, the braking device is allowed to be inoperative.

2. Fusing according to allocation type „2“, DIN EN 60947-4-2. After a short circuit, the braking device must be suitable for further use. However, there is the danger that the contacts of the braking relay (braking contactor) weld. Therefore, if possible, these contacts are to be checked prior to applying again mains voltage to the device. If this check cannot be carried out by the user, the device has to be returned to the producer in order to have it checked.

The following dimensioning information refers to the below operating conditions:• Use of standard asynchronous motors• Braking time not exceeding 20s• Braking current not exceeding 2.5x INOM of the motor.• Cyclic duration factor (c.d.f.) not exceeding the value indicated in the data sheet.

Fusing according to allocation type „1“:As pre-fuses, we recommend to use line protection fuses (utilization category gL) or automatic circuit breakers with tripping characteristic B, C, D or K.Taking into account the maximum braking currents that occur (normally the rated device current), we recommend fuses according to table 2, column 3.

Note: Wiring cross-sectional area according to DIN VDE 0100-430, DIN EN 57100-430.

18 VB230/400-6/25/30L (LP)

Fusing according to allocation type „2“:The power semiconductors are to be protected by fuses of the utilization category gR (semicon-ductor fuses, high-speed fuses). However, since these fuses do not ensure line protection, it is necessary to use additionally line protection fuses (utilization category gL).As for the dimensioning of the line protection fuse (gL), please refer to table 2, column 3. To protect the semiconductors it is necessary to select gR-fuses featuring cutoff-I²t-values of the ranges indicated in table 2, column 4. In this connection, the fuse rating of the selected fuse should not be smaller than the braking current to be expected (rated device current).

Note 1: On the basis of the recommended I²t-value, braking current, and possibly the c.d.f., the fuse supplier is able to select a suitable type. Due to the great variety of producers, sizes, and types, PETER electronic does not recommend any particular fuses.

Note 2: If the fuse or cutoff-I²t-value is selected too small, it may happen that the semiconductor fuse reacts during braking.

For intermediate values please refer to table 3.

Warning:

When setting up a machine or during commissioning, it is possible to carry out 4 braking operations in succession, i.e., with rated device current and at a braking time of 10s. After such operating conditions, however, the device needs a recovery time of 15 minutes.
